new player needs to understand some concepts...

1)White has openings and Black has defenses right?

2)Let's say i play (as white) e4, black plays e5, i play Nf3, he then plays Nc6 and i play Bb5...which is the ruy lopez onening right?If that is the ruy lopez opening, who is playing that?I mean after a6 the computer says Ruy Lopez:Morphy defense...so black wasn't playing anything himself?ahhaha

3)In order to be a better player i guess i have to learn the openings...but let's say i want to play the ruy lopez as white(i guess you can play it only as white... idk what i'm saying) but after i play e4 he plays something else instead of e5...what do i do? ahhahahah

1) yes

2) yes; both players; black played a certain variation of the Ruy Lopez

3) either find another opening to play, or just follow standard opening principles even if you don't know any theory.

could you suggest me what openings/variations to study?or tips

Forget about specific openings and start to study the basic opening principles: https://www.chess.com/article/view/the-principles-of-the-opening

Uhh idk, I don't really study openings, I just kinda wing it and hope for the best. As a beginner, as long as you learn and follow opening principles then you'll be ok even if you don't know any theory.

learn 3 openings really well

1. white opening

2. black response to 1. e4

3. black response to 1. d4

then learn how pieces can help each other to attack/defend weak squares or pawns and also learn tactics.

man, I just move chess pieces.   ha.  probably can tell based on my rating.

whatevs...e4 is the only opening i'm aware of.  if I play black, most of the time I just copy what white does for the first 6 or 7 moves.   Is that bad?

my advice is to play a very strong computer and see how they open against different variations!! this doesn't go to say play like a computer does I'm just saying use that as a guideline because in openings computers almost always know best!!

THIS IS WHAT HAPPENS WHEN A STRONG COMPUTER COMES MY WAY....

Sometimes!

Don't worry too much about following specific lines.  Just follow general principles:

1. Develop your pieces

2. Control the center

3. Don't move the queen out too soon

4. Don't move the same piece twice in the opening

5. Feel free to violate these rules if you have a genuine tactical reason to do so; for example, it's OK to bring your queen out on the second move if your opponent walks into the Fools Mate:

HA Pulp..I got ya.    ok, here's another question...when is "the opening" considered no longer an opening?

When you reach a closed position

When the pieces are mostly developed and middle-game tactics and/or maneuvering have begun.

(1) No. As I understand it, an opening is any position early in the game that can be arrived at, which means it can be named after either White has played or Black has played. For example:

1. c4 {English Opening. The position is named after White moves.}

1. Nf3 d5 {Réti Opening. The position is named after Black moves.}

For example, a book on "openings" has positions like the French Defense and Alekhine's Defense, which are named after Black moves, as well as positions like Polish Opening and Ponziani Opening, which are named after White moves. As for opening *names*, however, *usually* it is called an "Opening" or "Attack" after White has played, and "Defense" after Black has played. For example:

1. d3 {Mieses Opening. The position is named after White moves.}

1. d4 d5 2. Bg5 {Levitsky Attack. The position is named after White moves.}

1. e4 c5 {Sicilian Defense. The position is named after Black moves.}

(2) The player who moves into the named position is choosing to play that opening. In your example, White plays the Ruy Lopez if he plays 3. Bb5, but if he plays 3. d4 instead then White is playing the Scotch Opening.

(3) Neither player can force any particular opening, at least not under normal conditions. For example, as Black you can't force a Ruy Lopez--only White can do that by choosing to play 3. Bb5 after the preliminary position is set up; White could just as easily play 3. d4 or 3. Nc3 or 3. Bc4. Similarly, White can't force a French Defense because Black doesn't have to play 2...e6 after the preliminary position is set up; Black could just as easily play 2...d6 instead. That's why players are often interested in subjects like "forcing lines" (https://www.chess.com/forum/view/chess-openings/solid-forcing-lines-against-van-t-kruijs-opening) and "anti-Sicilians" (https://www.chess.com/forum/view/general/any-anti-sicilian-lines).

Now you know one reason why openings are rough: there are so many possibilities at almost every move, many of them commonly played, so to be good you should know something about all the common ones, at least. ("It could blow at any seam!")

That's the same stupid look I got on my face about 40 yrs.  ago when my coach NM Gary  Sanders asked me :  Do you know when the opening ends and the middle game begins.

The answer is when White or Black makes the first move  of the middle game plan of attack.  It is usually a pawn break move at a strategic point(s) in the pawn structure, that is a liberating move or an attack into the opponent's position.  A pawn break is when 2 opposing pawns stand in mutual capture  positions.  that means that the  white  pawn can capture the black pawn and vice versa.

That is how you know that the opening is over and the middle game has begun,

For someone seeking help with choosing openings, I usually bring up Openings for Amateurs by Pete Tamburro (2014).
http://kenilworthian.blogspot.com/2014/05/review-of-pete-tamburros-openings-for.html
https://chessbookreviews.wordpress.com/tag/openings-for-amateurs/
I believe that it is possible to see a fair portion of the beginning of Tamburro's book by going to the Mongoose Press site.
https://www.mongoosepress.com/excerpts/OpeningsForAmateurs%20sample.pdf
"Each player should choose an opening that attracts him. Some players are looking for a gambit as White, others for Black gambits. Many players that are starting out (or have bad memories) want to avoid mainstream systems, others want dynamic openings, and others want calm positional pathways. It’s all about personal taste and personal need.
For example, if you feel you’re poor at tactics you can choose a quiet positional opening (trying to hide from your weakness and just play chess), or seek more dynamic openings that engender lots of tactics and sacrifices (this might lead to more losses but, over time, will improve your tactical skills and make you stronger)." - IM Jeremy Silman (January 28, 2016)
